LUBRICATOR.

Specification of Letters Patent. Patented N 0V. 13, 1917.

Application filed May 12, 1917. Serial No. 168,195.

To all whom it may concern:

Be it known that I, BURL V. ROSE, a citizen of the United States, residingat Ridgeway, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to lubricators, and more particularly to a mechanically operated lubricator designed for use on reciprocating parts of machinery that require profuse lubrication and, by reason of their movement, are dangerous to lubricate by the ordinary hand lubricator.

One of the objects of the invention is to,

provide a grease cup of the plunger type, the stem of the plunger being provided with serrations to form arack bar, while the body of the cup is provided with mechanically operated means for imparting movement to the plunger, so that the grease within the container or cup may be ejected in the required quantity. I

A further object of this invention is th provision of a lubricator which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily sub jected.

For a full description of the invention and the advantages and merits thereof, ref erence is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is a side elevation of the device constructed in accordance with my invention.

is screw threaded to receive a cap 4 pro Fig. 2 is a fragmentary vertical section vided with a central circular opening 5. Within the cup is a plunger 6 for engagement with the grease or oil carried by the cup, whereby the grease or oil may be ejected from the cup when the plunger is actuated. Secured to the plunger is a plunger rod which extends upwardly through the opening 5 in the cap, and this plunger rod has teeth or serrations thus forming a rack bar 7 of the plunger rod. 7

F astened to the cap 4: in any preferred manner is a casing 8 having a central opening in its top through which the rack bar 7 projects. Extending through the casing 8, and j ournaled in the sides thereof, as shown by Fig. 5 of the drawing, is a shaft 9 having a tooth 10 formed thereon for engaging the teeth ofthe rack bar 7, so that when the shaft 9 is rotated, the rack bar will, be actuated either upwardly or downwardly ac? cording to the direction of rotation of the shaft 9. The outer end of the shaft 9 carries a gear 11. v 1

Detachably mounted on the side of the cup 1 is agear box 12 which is closed on all sides except the side engaging the body of the cup, so that when the gear case box is mounted in position, the side of the cup 1 will form one side of the gear box as shown to advantage in Fig. 2 of the drawing. The upper and lower walls of the gear box are cut out as indicated at 13 in Fig. 4: so that the upper and lower walls will fit snugly around the cup and the gear case'is then attached by a band 14 embracing the gear case, and the cup 1 and joined together at its ends by a bolt 15.

Disposed vertically'within the gearcase 12 and journaled in the upper and lower walls thereof is a countershaft 16, the upper end of which carries an eccentric worm 17 in mesh with the teeth of the gear 11; this worm being designed to impart movement to the gear 11 equal to the length of the circular pitch upon each revolution of the ec-' centric worm 17. Within the gear case, the shaft 16 carries a pinion 18 in mesh with a single tooth 19 of a crown gear 20, the latter being mounted on a stud shaft21 journaled in the outer wall of the gearcase 12. This single tooth carried by the crown gear meshes with the teeth of thegear 18, so that one revolution of the crown gear will impart merely a partial movement to the shaft 16,- the ratio being. preferably 16 tol, so

l ti of the shaft will impart a movement to the crown gear equal to the distance between the teeth; Mounted on the outer end of the shaft 22 is a star wheel 25,

-the rad ating fingers of which areadapted to engage a convenient pro ection or machinery part, so that thewheel will be rotated when it engagesthe said projection" upon thereciprocation or movement orthe 7 part of the machinery to whicli the lubri-- cator is attached. Itwill beseen, therefore, that the star'wvheel will impart'move- -ment to the shaft 22, and the latter, through" the medium of the tootlrQ3 will impart movement to the cro-wngear 20. The crown gear, by having a'singl'e tooth 19-.engage With the gear 18, Will-impart rotary move-' 'ment to the shaft 16 which carries the gear 18. "The'eccent *icworm 17, carried by the 7 shaft 16 at the exterior of the gear case, will turn theshaft 9 through the-medium of the gear 11, and this shaft, inturmwill actuate the rack bar-to force the piston downwardly within the 'lubricator for ejecting the lubricant. This construction will 4 cause a very slight movement ofthe piston when the machinery is moving at a great rate of speech-and it'will be apparent that the-gear box mav be quickly and easily re-' *mored-byi detaching the 'band' 14', so" that Y gears of different SIZGS' and different pitches may be" placed within thegea'r'box to vary 3 "th'espeed of'movement of the plunger 6 ae-' cording to the' sp'eed' of the machinery-to which the lubricator is attached; Thus, the

' lubricant'may be adjusted to the-'eX-ac't'de- 'grearequired.

From the-foregoing it will be 'obser'ved that a very-simple and 'durablelubricatorhas been pro ided. the details of which em- -body the preferred-form. I desire it'to be understood, however that slight changes in I the minor details ofconstruction 'mayf be made without departing from the spirit of the invention or the scope of the-claims here unto appended. l I claim:
